High CVSS 7

CVE-2026-49162

Microsoft Windows 11 24h2

Use after free in Microsoft Brokering File System allows an authorized attacker to elevate privileges locally.

What this means

Exposure
Exploitable with local access to the machine, with an ordinary user account and with no action from the victim. The attack does require particular conditions, which makes it less systematic.
Impact
An attacker can read sensitive data, modify or destroy data and take the service offline.
Weakness
Already-freed memory is reused, letting the attacker reclaim it and hijack execution.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
